Greaton Bunkie Boards, Box Springs & Mattresses

The right box spring height depends on three things: how thick your mattress is, what kind of bed frame you're using, and how high off the floor you want the finished bed to sit. Greaton's box spring line spans 2" all the way to 10" — that range exists because "one size fits all" has never been true for foundations, and picking the wrong profile is the most common reason for returns in this category.

Before ordering, measure your current setup. Stand a tape measure on the floor and mark the top of your bed frame's side rails — that's your starting height before the foundation and mattress go on. Then add your mattress thickness. If the total puts you above 30"–32" from floor to mattress top, you're likely looking at a stepping-up situation that some people love and others don't.

2-Inch Foundation — For Tall Mattresses and Platform Setups

The 2" low-profile option (like the 2-Inch Queen Box Spring Assembled, measuring 79"×60"×2") is for buyers who already have a tall mattress — 12" or thicker — or a platform bed frame that sits high on its own. Adding a 2" foundation gives you solid wood support and noise-free Amish-built construction without stacking excessive height. It's also the right call if you're replacing a box spring on a platform frame that was designed to work with a foundation rather than slats alone.

4" to 4.5" Mid-Profile — The Most Versatile Option

A 4.5" foundation threads the needle between too low and too tall. Pair it with a 10"–12" memory foam or hybrid mattress and a standard metal rail frame, and you're sitting at roughly 22"–24" total — comfortable for most adults to get in and out of bed without feeling like they're climbing. The 4.5-Inch Cal King Box Spring Flat-Pack (83.5"×71.5"×4.5") ships in flat-packed pieces and assembles tool-free, which matters when you're dealing with a cal king that won't fit through a narrow hallway in one piece.

8" to 10" Standard Profile — Traditional Frames and Innerspring Mattresses

This is the classic setup: a traditional metal rail frame, an 8" or 10" Amish-made wood box spring, and an innerspring or hybrid mattress on top. The 8" Cal King Box Spring Assembled (84"×72"×8") arrives fully assembled in four pieces that fit through standard doorframes. The 10" full-size option (74.5"×53"×10") is the tallest profile Greaton makes and works best on low-profile metal rail frames where you want the bed to sit at a conventional height — roughly 26"–30" from floor to top of mattress.

One thing worth saying directly: if you're buying a thick memory foam mattress (12"–14" thick), an 8" or 10" foundation is probably too much. Your bed will sit high enough that it feels awkward, and some people won't notice until the mattress arrives. A 2" or 4" foundation — or even Greaton's wooden bed slats — is the smarter pairing with a tall foam mattress.

A Simple Measurement Before You Order

Measure the interior height of your bed frame from the floor to the top of the side rails. Add your mattress thickness. Add your planned foundation height. If that total is between 24" and 30", you're in a comfortable range for most adults. Under 20" feels low; over 32" starts to feel like you need a running start. These aren't rules — but they're a reasonable check before clicking purchase.

All Greaton box springs use solid wood construction with snug-fitting joints and no metal connectors. That's not a feature description for its own sake — metal connectors are exactly what loosens over time and produces the creaking that drives people to Reddit looking for solutions. The wood joint design removes that failure point entirely.

RV mattress sizing is not the same as home mattress sizing, and getting it wrong is the single most common reason people return an otherwise good mattress. A standard queen measures 60"×80". An RV short queen measures 60"×75" — five inches shorter. That difference matters more than it sounds when your mattress platform has a fixed frame with no give. Measure your platform's interior dimensions before ordering. Every time.

Greaton's RV mattress line covers the most common non-standard dimensions you'll encounter in travel trailers, Class A and Class C motorhomes, and fifth wheels. Here's a size reference to match your rig type to the right product.

RV Size Reference Chart

The 10-Inch RV Mattress Short Queen (75"×60"×10", 57 lbs) is the thickest option for the most common main bed size. The 10-Inch RV Mattress Compact Bunk (72"×28"×10", 25 lbs) is the narrowest. Note how dramatically the weight changes — 57 lbs vs. 25 lbs for the same 10" thickness, purely because the surface area differs. That matters when you're moving a mattress in and out of a confined RV sleeping area on your own.

How Thick Should Your RV Mattress Be?

For bunk beds and folding wall-mounted systems, keep to 4"–6". Anything thicker will fight the clearance when the bunk folds up, and the weight compounds the problem. On a fixed bunk platform where headroom isn't an issue, 8" is a reasonable step up.

For main beds — the short queen or full-size sleeping area — 8" to 10" is where most buyers land. The 8-Inch RV Mattress (75"×30", 38 lbs) provides a meaningful improvement over the typical OEM mattress, which runs 4"–5" and uses lower-density foam. The 10" option adds another layer of support and is worth considering if you're a full-timer sleeping on the mattress every night versus a weekend camper using it 30 nights a year.

What to Do When Your Platform Doesn't Match Standard Dimensions

Older rigs and some imported travel trailers don't conform to any standard size. Greaton's high-density foam can be trimmed to fit non-standard frames — a sharp utility knife and a straightedge handle it cleanly without specialized tools. Don't try to force an oversized mattress into a frame. A mattress that's bent at the corners to fit will develop a permanent crease at the fold point, and no amount of sleeping on it will flatten that back out.

All Greaton RV mattresses are made in the USA from high-density foam with a breathable standard fabric cover. Medium firm feel — not the soft plush that sounds appealing but collapses under sustained use in a warm RV environment. If you need the gel memory foam variant for heat management, that option exists in the same size range through the Greaton store on Amazon.

The right mattress topper depends on what problem you're actually trying to solve. A 1" convoluted foam topper and a 2" copper-infused memory foam topper are both toppers, but they do meaningfully different things — and buying the wrong one is a waste of money. Here's how to match Greaton's four foam types to your specific sleep situation.

1 Inch Convoluted Foam — Minor Surface Adjustment, Maximum Airflow

The convoluted design — the egg-crate peak-and-valley pattern — creates channels for air to move through the foam surface. This is the single most effective topper design for temperature regulation. The 1-Inch Convoluted High Density Foam Topper (queen, 80"×60"×1", CertiPUR-US certified) and the 1-Inch Convoluted Gel Memory Foam Topper (queen, 80"×60"×1") both use this structure. At 1" thick, neither will dramatically change the feel of your mattress — that's not what they're for. They're surface adjustments, not mattress replacements.

The plain convoluted foam (green, B0GV167HQS) works for anyone who sleeps warm and has a mattress that's already comfortable but runs hot. The gel convoluted variant (blue, B0FNRZ12LG) adds gel particles to the foam that absorb and dissipate body heat — a meaningful upgrade if heat is a consistent issue rather than an occasional one. Users on Amazon and Reddit's r/Mattress community have specifically called out Greaton's convoluted topper as the "best price" option for hot sleepers in this category.

1 Inch Copper-Infused Memory Foam — Cooling With Pressure Relief

The 1-Inch Copper-Infused Memory Foam Topper (twin, 74"×38"×1", CertiPUR-US certified) uses copper-infused foam with an airflow channel design. Copper is highly thermally conductive — it pulls heat away from the body faster than standard memory foam, which is notoriously poor at heat dissipation. The copper infusion also helps resist moisture. This is the premium 1" option: it costs more than the convoluted foam variants, and it's worth it if you want the conforming feel of memory foam without the heat buildup memory foam typically creates.

Note: this topper requires up to 72 hours to fully expand after unpacking. Don't judge it by how it feels on day one.

2 Inch Foam — Noticeable Feel Change

The jump from 1" to 2" is significant. A 1" topper adjusts the sleep surface temperature; a 2" topper actually changes how the mattress feels. The 2-Inch Gel Memory Foam Topper (twin, 74"×38"×2", CertiPUR-US certified) is the right choice if your current mattress is too firm and you want memory foam conforming — the gel particles in the foam help manage heat while the 2" depth gives the foam enough volume to actually contour around your shoulders and hips.

The 2-Inch High Density Medium Firm Foam Topper (twin, 74"×38"×2", CertiPUR-US certified) takes a different approach. It's denser and firmer rather than conforming — the right pick if your mattress has softened over time and you want to restore some support rather than add plush. Think of the gel topper as "softer feel plus cooling" and the medium firm foam topper as "support restoration."

Which Problem Maps to Which Topper

• Sleeping hot on an otherwise comfortable mattress — 1" convoluted foam or 1" convoluted gel memory foam
• Sleeping hot and want memory foam feel — 1" copper-infused memory foam
• Mattress too firm, want noticeable softening — 2" gel memory foam
• Mattress too soft or has sagged, want support back — 2" high density medium firm foam
• Minor surface upgrade on a budget — 1" convoluted high density foam (entry option, full size at 74"×53"×1" also available, B0GXFSLGXB)

Every foam topper in Greaton's line is CertiPUR-US certified — independently tested and confirmed free of ozone depleters, heavy metals, formaldehyde, phthalates regulated by the CPSC, and high-VOC emissions. That's a real third-party certification, not a brand marketing label. It matters especially if you're sensitive to off-gassing from new foam products, which is a common concern in enclosed spaces like RVs or small bedrooms.

One honest limitation worth naming: none of Greaton's current toppers are available in sizes beyond twin and queen in the 2" variants. If you need a 2" topper for a king or cal king setup, check current availability on Amazon — the line is expanding. The 1" convoluted options do come in full size (B0GXFSLGXB, 74"×53") as well as queen.
