What to Confirm Before Ordering
Order by measurements, not by mattress name
RV mattress names are not always consistent across manufacturers. “RV queen,” “short queen,” “bunk,” and “RV king” can refer to different dimensions, so order by the measured width × length before placing an order.
Measure the platform, not the mattress
Old RV foam mattresses compress and shrink. Measure the platform surface directly with a tape measure, not the mattress lying on it.
Account for any modifications
Pre-owned units may have modified platforms. Measure directly — don’t rely on factory specs, previous owner notes, or floorplan assumptions.
Check corner shape on every mattress platform
Look at all four corners of each mattress platform. Bottom bunks near ladders, walls, cabinets, and access points may have notched or angled corners that affect how a replacement mattress will sit on the platform. Ensure all four corners are square, as radius, notched, and angled cuts are not available at this time.
Confirm moving parts and closed-position space
If the mattress platform lifts, folds, slides, or stores away, check the space in both the sleeping and closed positions. A thicker replacement mattress may interfere with slide-outs, cabinets, doors, Murphy beds, lift-up storage platforms, or folding mechanisms.
Check bunk side rails
For bunk platforms with raised side rails, measure the usable depth inside the rail to ensure the replacement mattress will not sit too tall or reduce safe headroom.
Why Upgrade the Factory Mattress in the Reflection 150 Series?
Factory RV mattresses are engineered for a specific purpose: lightweight, pre-sized for the platform, and structured to keep the coach’s purchase price competitive. For occasional weekend trips or owners focused on towing payload, the factory mattress serves its role well. The tradeoff becomes more noticeable on longer stays or in warmer conditions.
The Reflection 150 Series is positioned as a value-premium fifth wheel for couples and downsizing full-timers. Owners who use the 295RL for extended seasonal stays or full-time living spend more cumulative nights on the mattress than a weekend camper would. The 295RL’s 60×80 platform shares dimensions with the standard residential queen, so replacement mattresses are available across all four PolarBed product lines via custom size order.
What PolarBed Does Differently for RV Sleep
PolarBed mattresses are built around the conditions that make RV sleeping difficult: non-standard platform sizes, bunk rail constraints, and trailer interiors that heat up faster and retain warmth longer than a home bedroom. Every product line is available in custom sizes for platforms that do not match any retail standard.
- PUP 6″ — Ultra-slim cooling foam designed for tight overhead space where a thicker mattress will not fit. The practical first choice when usable height above the platform is the limiting factor.
- CUB 10″ — HD foam with Conductive Cooling Memory Foam. Fuller support where available height allows, without the weight or cost of a coil system.
- MA 12″ — Pocket coil pillow top with Cool Gel Memory Foam. Coil layers allow airflow through the mattress core, which is especially relevant in warm trailer conditions. Recommended for the main bedroom upgrade.
- PA 15″ — 2,400 Nano-on-Coil luxury pillow top. Premium main bedroom upgrade where headroom allows. Not available for bunk or twin platforms.
- Custom sizing — All four product lines support custom-cut orders. Order by your confirmed platform measurements, not by the mattress name printed on your factory foam.
Sleep Location Mattress Options
Main Bedroom Options — 60″ × 80″ Custom Size
The 295RL main bedroom platform measures 60″ × 80″, confirmed from Grand Design’s official spec page. This matches the standard residential queen footprint. All PolarBed product lines are available via custom size order.
Choosing the Right PolarBed Line
| Line | Thickness | Cooling Technology | Best For |
|---|---|---|---|
| PUP | 6″ | Cooling Memory Foam | Tight overhead space, bunk rails, and low-profile RV sleep areas |
| CUB | 10″ | Conductive Cooling Memory Foam | Bunks where available height allows a fuller mattress; double-size platforms; some main beds |
| MA | 12″ | Cool Gel Memory Foam + Pocket Coil | Recommended main bedroom upgrade; bunks only where available height allows |
| PA | 15″ | Cooling Pillow Top + 2,400 Nano-on-Coil | Premium main bedroom upgrade where mattress height is not restricted |
