The Best Full Mattresses

Sitting compression measured 2.69–2.81 inches, and lying edge support was rated outstanding. The final rating reflects those results and the 14-inch hybrid construction.

Sinkage measured 2.59–2.69 inches on a 14-inch profile. That result was assessed alongside the official medium-firm feel, hybrid support system, zoned-lumbar layer, and the position- and weight-specific fit results.

Pressure maps showed side-sleeper mean/max pressure of 0.098–0.102/0.73–0.77 PSI, back 0.059–0.061/0.36–0.38 PSI, and stomach 0.069–0.071/0.32–0.34 PSI. Sinkage measured 2.59–2.69 inches (very deep), with a 5.25-inch comfort layer on a 14.00-inch profile. The score reflects those results alongside official comfort-layer construction and the medium-firm hybrid design.

Peak-to-peak acceleration of 6.65–6.93 m/s^2. Response mostly recovered in 0.29–0.31 sec and fully recovered in 0.59–0.61 sec, and bounce measured 8.87–9.23 inches, so the shared-bed score weighs both measured transfer and owner partner-disturbance feedback.

The surface mostly recovered in 0.29–0.31 seconds and fully recovered in 0.59–0.61 seconds. Bounce measured 8.87–9.23 inches and sinkage measured 2.43–2.53 inches. Owner descriptions of easy repositioning aligned with the measured responsiveness.

Sinkage measured 2.43–2.53 inches on a 12.5-inch profile; response mostly recovered in 0.29–0.31 sec and fully recovered in 0.59–0.61 sec, with bounce at 8.87–9.23 inches (Moderate). Those support and alignment signals were assessed alongside official firmness and support-core details plus repeated owner reports about back support, sagging, hip sink, or firmness mismatch.

Pressure maps showed side-sleeper average/max pressure of 0.118–0.122/0.79–0.83 PSI, back at 0.078–0.082/0.47–0.49 PSI, and stomach at 0.098–0.102/0.85–0.89 PSI. Sinkage measured 1.99–2.07 inches, with a 5.0-inch comfort layer on a 14-inch profile, so the Midnight Luxe delivers real cushioning without becoming a slow, deep-sink foam bed.

Sitting compression measured 2.69–2.81 inches, and lying edge support was rated Outstanding. The reinforced perimeter makes the Midnight Luxe an exceptional choice for couples who want more usable surface area.

Motion-transfer testing measured peak-to-peak acceleration at 5.64–5.88 m/s². The memory-foam comfort layers and individually wrapped coils keep partner movement much quieter than on many coil mattresses.

The all-foam build has no coil unit, so small movements should be muted better than on a springier budget hybrid. Motion isolation is one of the clearer strengths as long as you do not expect the mattress to feel bouncy.

Brooklyn Bedding lists a 120-night trial, a 30-day minimum before return, a $99 mattress return fee, free direct shipping, and limited lifetime warranty language. Clearance, retailer-channel, and non-contiguous-U.S. terms can differ, keeping the protection below the top bands.

Choose height carefully: the 12-inch and 14-inch versions have more foam depth for adults, while the 6-inch and 8-inch options are more limited comfort surfaces. Brand-hosted customer reviews repeatedly praise comfort in RV, bunk, guest-room, and budget uses. The 12- and 14-inch builds provide the clearest adult pressure-relief fit; the 6- and 8-inch versions remain better suited to lighter loads and occasional-use settings.

Motion-transfer testing was exceptional, with peak-to-peak acceleration of 2.07–2.15 m/s². The all-foam build and low 6.58–6.84-inch bounce help quiet partner movement, though that same muted feel is less responsive for sleepers who want spring.

Pressure-relief testing landed at the top of the range. The 2.12–2.20-inch measured sinkage and 6-inch comfort system fit a medium foam surface that gives shoulders and hips more room than AS2, while owner fit reports keep the pressure-relief guidance focused on side and back sleepers.

The AS3 has moderate 2.12–2.20-inch sinkage, a 12-inch profile, zoned transition foam, and quick enough recovery for many side and back sleepers. The medium feel and low 6.58–6.84-inch bounce are the reasons stomach sleepers and heavier bodies should compare firmer builds.

Sitting-edge compression measured 2.21–2.29 inches, and stability while lying near the edge was outstanding. The foam encasement keeps the perimeter exceptionally secure for sitting, sleeping near the side, and using the full mattress width.

Sinkage measured 1.99–2.07 inches on an 11.50-inch profile. The Lumbar Zone design and two coil layers provide additional structure through the center third of the mattress, producing the lifted support reflected in the alignment assessment.

The surface mostly recovered in 0.196–0.204 sec. and fully recovered in 0.39–0.41 sec. Bounce measured 12.28–12.78 inches and sinkage measured 1.99–2.07 inches. Those results match the easy-repositioning experience described by many owners.
